Why the packaging of DNA is necessary: A. The bacterium E. coli is a Gram-negative rod that is 1μM x 2μM. Each E. coli cell cont

ains a chromosome of 4 x 106 bp of double-stranded DNA. Since 1 kilobase pair (kbp) of double-stranded DNA is 0.340μM in length, what is the length of the E. coli?

Answer:

The RecBCD enzyme of Escherichia coli is a helicase-nuclease that initiates the repair of double-stranded DNA breaks by homologous recombination. It also degrades linear double-stranded DNA, protecting the bacteria from phages and extraneous chromosomal DNA.

ASHA 777 [7]

Answer:

Mitosis

Explanation:

Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the separation of the duplicated genetic material carried in the nucleus.

andrew11 [14]

Answer:

Trisomy

Explanation:

A trisomy is a type of polysomy (presence of three or more copies of the chromosome rather than the expected two copies) in which there are three copies of a particular chromosome, instead of the normal two. A trisomy is a also a genetic disorder and a type of aneuploidy (an abnormal number of chromosomes either an increase or a decrease). Examples include trisomy 21 (Down syndrome), trisomy 18 (Edward syndrome), trisomy 13 (Patau syndrome)

The Earth's oceans act as a climate moderator. Oceans do this in many ways, including ALL BUT one method listed here. That is
Aleks04 [339]

A) evenly distributing solar radiation.

The oceans do not evenly distribute solar radiation on earth. Actually solar radiation on earth is never evenly distributed due to the spherical shape of the globe and titled nature of earth on its axis. However, oceans attempt to disturbed the solar energy from solar radiation around the earth through ocean currents. Nonetheless evenness is never achieved, and ideally cannot be reached as long as earth remains dynamic.

Explanation:

Usually the equatorial region is heated faster and warmer than higher latitudes. The ocean waters in the equatorial regions are, therefore, warmer and these currents head towards the poles (on ocean surface waters) as cooler oceans currents from the poles replace these waters at the equator (upweling from deeper denser waters in the ocean). This ensures the distribution of solar energy around the world. In addition, water evaporating from ocean surface carry with them energy that is transferred to the atmosphere. The atmosphere, on other hand, distribute this energy through wind currents.

What is apoptosis? A. The proliferation of cytotoxic T-cells. B. The receptor on a cytotoxic T-cell that recognizes MHC molecule
castortr0y [4]

Answer:

Option-C

Explanation:

Apoptosis is a genetically controlled process taking place in the multicellular organisms which is marked with the self-destruction called or programmed cell death.

During apoptosis various physiological and morphological changes take place in the cell such as fragmentation of nuclear DNA, nucleus, shrinkage of cell and mRNA decay.

Since apoptotic cell undergoes cell death which is genetically controlled or programmed by the genes, therefore, apoptosis is known as the programmed cell death.

Thus, Option-C is the correct answer.
